Gwen joins Total Drama Island because her younger brother dared her to and she thought that it would humor him, so she signed up. Once she was picked, she was quite angry. Gwen is aggressively defensive. People think that she is pessimistic, which she isn't, however, she steadfastly refuses to be cheerful. Truly, Gwen is not a bitter person, but rather guarded and cautious about whom she lets into her life. When she was tethered to Geoff in Trial by Tri-Armed Triathlon, she wound up revealing that she was never invited to a party, and sometimes wishes that she could be a party girl (something that Geoff sensed and wished to help her with). Gwen seems to give off the impression that she wants to join the crowd, but she is too cautious about who to let in and she could never fit right in, so she became a lone wolf who spends most of her time in solitude. Gwen is extremely "smart, independent, level-headed, and is able to soar through challenges without much difficulty." This ability allows her to become Total Drama Island's runner-up. She has also made several friends on the island. She harbors a dislike of Heather, who has done several cruel things to her, such as reading her diary aloud. The conflict between the both of them was one of the major ones in Total Drama Island.

When Gwen arrives, she is already disappointed and a little angry at the location of the island. Gwen seems to be displeased by several things, such as Geoff's happy attitude. Gwen attempts to ignore Trent as well, but can't help smiling at him, foreshadowing their relationship. Gwen almost immediately makes enemies with Heather when she addresses her as "weird goth girl," Cody, who she throws out of her cabin after he tries to flirt with her, and Lindsay, who she called an idiot. However, Tyler tries to comfort her by saying that she at least doesn't have to sleep next to Duncan. Gwen has a lot of interaction with Lindsay in this episode though. After Lindsay screamed that she saw a cockroach, DJ jumped on Gwen's bunk, and Gwen was impressed once Duncan killed a cockroach. While in the mess hall, Gwen questions to Chef about the bad qualities of the grub, only for Chef to smash her grub with a meat tenderizer.

In Not So Happy Campers - Part 2, Gwen is completely terrified when she jumped off the cliff. She once again had another bad interaction with Heather, when she asked her that if she was kidding when she refused to jump off the cliff, although she does not take it in a violent way like LeShawnadid. In The Big Sleep, Gwen was seen once during the 20K run walking, telling Harold not to walk beside her. After bloating in the buffet challenge, she told Trent that the Awake-A-Thon segment of the challenge would probably be over about an hour or less, after seeing Owen walk tired. With Trent's help, the two of them stay awake by revealing each other secrets and thoughts about several things and questions, hinting a relationship. They were sharing a very tender moment (and Gwen was about to fall asleep) but they were woken up and disturbed by the sleepwalking, naked Owen. By the 85 hour mark, Gwen is only one of the five people who are still awake. However, Gwen is extremely sad when Trent falls asleep, leaving only her and Duncan in the final two of the challenge. She managed to win the challenge, after Duncan took a snooze on "the can." Gwen fell asleep right when Chris announced the winner.
Gwen and Trent try to steal a moment at the Dock of Shame in Not Quite Famous.EnlargeGwen and Trent try to steal a moment at the Dock of Shame in Not Quite Famous.In Dodgebrawl, Gwen could barely stay awake for most of the episode, as she showed up late for breakfast, and immediately fell asleep when she sat down. When Heather was teasing the Bass, Courtney tried to throw her oatmeal at Heather but Heather moves a bit away and she gets Gwen instead. She participated in the challenge despite this in round one, where she got immediately thrown out by DJ, and did not go in again until round five, where she was in at the beginning until she got thrown out by DJ (again). She would have been out before that, but Cody selflessly jumped out in front of her when a dodgeball was heading towards her. She also got Courtney out for throwing oatmeal at her earlier in the episode during round five. LeShawna laughed along with Gwen, as LeShawna told Courtney she "messed with the wrong white girl!" This is the start of Gwen and LeShawna's friendship, which eventually leads up to LeShawna becoming Gwen's best friend. Gwen told Noah to shut up after her team lost the challenge and Heather agreed with her.

In Not Quite Famous, Gwen starts a more in depth conflict with Heather. Gwen gets angry when she immediately declares herself lead judge of the auditions. She is calmed (and smitten) by Trent, however, when he stole an extra muffin for her. Sometime later in the episode, Gwen is alone with her diary, but she gets bothered by Cody, who doesn't seem to want to leave her alone. To get away from everything, she and Trent go to the dock of shame, but the moment is interrupted by Owen and Cody. After they jumped in the water and splashed Gwen, she angrily leaves the dock saying she hated the island. On her way back, she confronts Lindsay, who is attempting to stop Gwen from going into the cabin so Heather may steal Gwen's diary. Later, at the Talent show, the song Trent sings is devoted to Gwen. When Heather reads out her diary to the entire viewing audience, it is revealed she has a crush on Trent, making her run away out of embarrassment. In spite of this, she borrows a red ant farm from Harold which she later uses to dump on Heather.

In The Sucky Outdoors, Gwen is so disappointed and embarrassed from the talent show that she doesn't even want to talk to Trent. To Heather, she is the one that needs to go next, but Trent disagrees. Possibly due to her embarrassment, Gwen doesn't have too many lines in the episode.

In Phobia Factor, Gwen admitted her fear of being buried alive, possibly due to her claustrophobia. For her part of the challenge, she had to be buried alive for five minutes. To help her out, Trent tried to talk to her via a walkie-talkie, but Gwen was left alone after Trent faced his own fear of mimes. Unintentionally, she is left in there much longer than just five minutes, since Trent forgot all about her. Right after, he faced his fear of mimes and went to talk to Chris. When Courtney is the only one left, Gwen attempts to make Courtney lose by making the green jelly sound more disgusting than it really was, which may have contributed to Courtney failing her challenge.
Against Gwen's willEnlargeAgainst Gwen's will, Cody becomes Gwen's canoe partner.In Up the Creek, when Trent and Gwen are just about to become canoeing partners, Cody manages to grab Gwen alone, and attempts to persuade her to be his partner. Cody and Gwen become canoe partners, but only because Trent was also snagged off-guard by Lindsay and Beth. Gwen also mentioned Cody was like a very annoying little brother. Cody asks Gwen out on a date, but after Gwen refuses several times, Gwen whacks Cody with her canoeing paddle in the groin. Cody finally realizes she likes Trent, but she whacks him in the groin again when Cody admits he made a bet with Owen to get one of her bras. Much later into the episode, Cody successfully gets Gwen and Trent into a canoe together, and Gwen awards him with one of her bras.

In Who Can You Trust?, Gwen gets paired with Heather for section one of the challenge. Obviously, due to their conflict, they don't trust each other. Heather rips off the bottom of Gwen's skirt when she is climbing up the mountain. Even though Gwen was embarrassed, the incident actually helped them win. She later got paired with LeShawna for the toboggan race down the cliff. She got scared about the route LeShawna took, as she wasn't blindfolded like she was, though she managed to win the challenge anyway.
Gwen refuses to trust Heather during the trust challenge.EnlargeGwen refuses to trust Heather during the trust challenge.In Basic Straining, Gwen wins invincibility for her team when she completes all the challenges without getting eliminated. Gwen laughs at Courtney when she runs outside to puke due to eating too much food. Gwen and LeShawna are shown to have become very close friends at this point, and Bridgette has also seemed to have joined the friendship as well. By winning the challenge, Gwen gained respect from Chef, even though Gwen wasn't too interested in it.

In X-Treme Torture, Gwen and Bridgette get in an argument about who wrote a certain haiku, where Gwen thought that Trent wrote the haiku. However, whenever Gwen asked Trent about the haiku, many of the campers stared awkwardly at her, due to her saying it in an awkward way. Bridgette believed it was Geoff. Both Gwen and Bridgette fail trying to get their crushes to admit the poem. Gwen was witness to Geoff telling Bridgette he didn't even know what a haiku was. The girls make amends after their failures, and hug, promising to figure out who wrote the poem together. Gwen and Bridgette thought that the only reasonable contenders would be Owen or DJ, due to Harold being... Harold, and Duncan having a big crush on Courtney. However, the person who wrote the haiku was who they never expected (Harold), proving Gwen and Bridgette wrong. Gwen had all this time because she did not participate in any parts, along with Bridgette.

In Brunch of Disgustingness, Gwen, along with nine other competitors, make it to the merge. She takes LeShawna's side, and is very pleased when Bridgette joins them. She does well in the challenges, and doesn't really complain about the dishes. Despite this, the girls still lose the challenge to the guys. Gwen and LeShawna lock later Heather out of the Girl's cabin that night.

In No Pain, No Game, Gwen begins to ignore Trent because of the fact that he left her buried alive several episodes ago. Trent then tells her she was the last person he'd leave buried alive if he had the choice. She is flattered, telling him that saying so was very sweet. They make up, and whisper to each other as their friends take on the most unbelievable dares. Gwen had the task of having her nose hairs pulled out forcefully, and she didn't make it past listening to New Age music torture. She voted Eva off, calling her a freak.
Upon falling into Heather's trapEnlargeUpon falling into Heather's trap, Gwen's heart is broken instantly.In Search and Do Not Destroy, Gwen had to get her key out of a group of skunks. Since Trent had already gotten his key, he helped Gwen out, which made Gwen admit her feelings towards Trent, and also caused them to kiss. Heather saw this as merely an alliance, causing Heather to kiss Trent to make Gwen and Trent believe each other as a jerk, a user, and a deceiver. Gwen told LeShawna about what happened, and LeShawna told everyone on the island about the incident. When Trent is eliminated Gwen, LeShawna and the other campers find out that Heather set them all up. Gwen and Trent say goodbye to each other on good terms, as Gwen tells Trent she didn't even vote for him. They try to share their first mutual kiss, but they are interrupted by Chris.

In Hide and Be Sneaky, she is still very sad of Trent being eliminated, but LeShawna comforts her. She says that, "nothing heals a broken heart like revenge" and Gwen smiles hoping to settle the score with Heather for Trent's unfair elimination. For her hiding place, she hid under a patch of grass. To prevent anything from seeing her, she punched an animal that got near her. Gwen was the 4th to last one caught, before Duncan, Geoff, and LeShawna. Owen accidentally tells her about the guys' alliance, causing the girls to unite and decide who to vote off. Her, LeShawna, and Bridgette all decide to vote off Duncan (although Bridgette was eliminated instead because Izzy didn't want to vote off Owen like Heather and Lindsay insisted).

In That's Off the Chain!, Gwen was playing Frisbee with most of the other competitors. When Heather announced her bike's name, Gwen said that the bike was a light as her brain was. Gwen's bike was described by Chris as "spooky, yet practical." Geoff rode Gwen's bike, but it ended up getting broken in a collision by Geoff. Gwen had to ride Owen's bike, but it was extremely low on the ground, causing dirt to run into her face. She was very amused when Lindsay cursed at Heather, and parted Lindsay on good terms.
Gwen has an encounter with a Real Psycho Killer.EnlargeGwen has an encounter with a Real Psycho Killer.In Hook, Line, and Screamer, Gwen and Duncan admit they have the same all-time favorite horror movie, which really creeps out DJ. When the challenge begins, in order for the campers to "survive," Gwen takes the leadership role. However, much to her annoyance, nobody listens (except Duncan). Eventually, when there are only her and Duncan left, Gwen decides to go to the kitchen and make herself a sandwich out of pure frustration. She has conversation with the Killer, thinking that he is not a real psycho killer. However, when everyone worriedly comes in the building, Gwen kicks the Killer in the face, causing him to leave, and making Gwen get solo invincibility.

In Wawanakwa Gone Wild!, she had to catch a duck. She fought over a net with Heather, but let go when she found duck bait. In a confessional, she said that all she has been through was barely worth the $100,000. However, the duck was seen to be a parody of the Roadrunner from Looney Tunes. Eventually, she is able to keep ahead of the duck and lure hit into the cage. This makes her win the reward of a big feast. Right when she is about to eat it, Owen runs into it when he is chasing after his chipmunk. Despite Gwen winning, she got the last marshmallow.
Geoff eventually gets Gwen to be in a happier mood.EnlargeGeoff eventually gets Gwen to be in a happier mood.In Haute Camp-ture, Chris asks Trent if he has anything to say to any of the campers left in the contest, and he wants to tell Gwen that he's rooting for her and misses her; he also admits that he is in love with Gwen and hopes that she's over the whole "kissing Heather thing." Izzy jumps in and says that if she were Gwen, Trent would be seriously maimed. Courtney says that Gwen is "okay" and smart, but isn't a "team player," comparing Gwen to herself and suggesting that she should be in Gwen's place. Noah tells her to get over it, and Courtney throws her drink at him, knocking him into the water. Lindsay says that Gwen was harsh sometimes, but in the end, she played an awesome joke on Heather, namely planting Harold's red ant farm in her bed. Bridgette says that she liked Gwen and LeShawna because of how nice they were to her when the teams merged, and wanted either of them to win. At the end of the episode, Lindsay, Cody, Bridgette (she also wanted LeShawna to win) and Trent wanted Gwen to win.

In Camp Castaways, she is sad LeShawna got eliminated in the previous episode. In the confessionals, she took herself to the limit, even saying she might die in the island she was on. Gwen made a raft eventually, and gave Duncan a raft ride in exchange for the egg Duncan had found. However, it just took them in a complete circle. After she admitted the worst thing she ever did, Heather questioned if Gwen was even her real name.

In Are We There Yeti?, she has to be paired with Heather. Despite their conflict, they eventually realize, only for the challenge, that they would have to cooperate. Eventually, after many cases where the guys and the girls stole each others' stuff, the girls were left with no supplies. Gwen thinks the guys are hiding behind a bush, but it turns out it was a Sasquatchanakwa. Heather and Gwen, that night, stole all the guys stuff, causing the girls to win invincibility. She parted on good terms with Duncan.
Gwen does Geoff's dare bravely.EnlargeGwen does Geoff's dare bravely.In I Triple Dog Dare You!, Gwen seemed that the sudden death challenge was a good idea. She performed some dares, and made Heather do some of her other ones. She did Ezekiel's dare (chew your own toenail slowly), Katie and Sadie's dare (kiss a dead fish), Cody's dare (drop a tray of ice into your underwear and let them melt), LeShawna's dare (walk on a tightrope while holding meat above shark-infested waters) and she saved her last freebie but didn't use it in able to have an alliance with Owen to try to get Heather eliminated for Geoff's dare (drink fruit punch from a toilet). After several rounds of dares, Gwen formed a temporary alliance with Owen in order to eliminate Heather, and Owen gave half of his twenty freebies to Gwen. Owen agreed because if she split the money with him if she won the game or if Owen won, she'd give him a box full of donuts. Eventually, after Heather performs many dares, she meets her downfall and Gwen finally makes it into the final two, with Owen happy as can be.
Gwen looks down and sees the sharks.EnlargeGwen looks down and sees the sharks.Trent helps Gwen climb the pole and retrieve her flag.EnlargeTrent helps Gwen climb the pole and retrieve her flag.In The Very Last Episode, Really!, Gwen said the island mostly stank, and the only good thing is that she did meet five sane campers. She said she would use the money to get into a good university, and split half the cash with Owen. After Owen promised a huge party, only Eva, Cody, LeShawna, and Trent remain on her side. Gwen wore the chicken hat for the race. Gwen had a good start, taking an easy lead but after Heather put butter on her pole, it stopped her for a bit, until Trent wiped it off. Gwen had a little daydream about Trent but LeShawna told her to knock it off as she got the flag, taking the lead. For the next challenge, she got one of the eggs and had to cross a plank to the other side without dying. Heather, though found Justin and took of his shirt, distracting both her and Owen. Gwen stops being distracted and gets a good lead. Owen later stops to run to the bathroom after having a brownie that Heather was supposed to give Gwen to make her feel sick to her stomach. Apparently, Gwen gave it to Owen making him stop. She was winning until Owen gets motivated by the brownies, causing her to be the runner up, but regain confidence in Trent. At this moment, Trent lifts Gwen onto his shoulders and convinces her to go out with him. Gwen finally agrees. At the end of the episode, Gwen tries to be kind to Heather, but playfully reminds her that she still stank literally and metaphorically.

In an alternate ending to The Very Last Episode, Really!, Gwen is the winner. After Owen knocks her down, Trent walks over and encourages Gwen to get up and keep fighting, saying that she shouldn't lose this thing because she is angry. They stare at each other for awhile and Gwen finally smiles while Trent helps her up. They continue to stare at each other until she hears Owen say "Ooh brownies I'm coming to get you!" She then says she will never win, but Trent tells her to run. Owen's side begins to cheer as Owen makes it to the finish line. As Izzy was outside the finish line, Owen ran into her and stopped there, allowing Gwen to pass him and win Total Drama Island. She is then awarded the final marshmallow and Owen gives her a hug. Owen is disappointed that there isn't going to be a party, but then Gwen says that after her studies she is going to throw a party and everyone is invited (except Heather). Owen then asks if she is going to take someone special, to which she replies, "Only if he will go with me," referring to Trent. Trent and Gwen officially become a couple and hug. Then, the guys throw Chris off the dock and Gwen tells Heather that she has to be happy for that, before telling her that she stinks.

In Total Drama, Drama, Drama, Drama Island, Gwen first laughs about Heather's smiley face on her bald head and later sides with Trent and LeShawna (her current closest friends in the island), although she actually never finds the case. Her group is the only one to see Heather being attacked by Beavers, but they laughed at her and continued to move on. Due to not being able to destroy the fine print, she must compete in Total Drama Action against her will.

Gwen assures Trent that both of them will not get too competitive when on different teams, in Riot On Set.Gwen returns to compete for one million dollars in Total Drama Action. Gwen did not share a bunk with anyone after the first episode, due to Bridgette being voted off. She starts out being as close as ever to Trent, her now-official boyfriend, but things quickly get tense in Alien Resurr-eggtion when Trent becomes jealous of Gwen and Duncan's friendship. Gwen notices Trent going out of his way to fit into their conversations and failing miserably, which makes her feel awkward. Despite the tension, Trent proves his worth when he saves Gwen's lucky necklace from falling in the sewers, sacrificing his potential win for the challenge. Gwen is so awed by his devotion that she gives Trent her necklace as a gift, saying it looks good on him. She and Trent win the challenge, but in a shocking twist, the two winners are now forced to become founders of the two new teams for the season, meaning Trent and Gwen have to compete against each other, much to their displeasure.

In Riot On Set, Gwen becomes the captain of the Screaming Gaffers team. She picks Duncan, LeShawna, Harold, DJ, and Heather to form her team. Because Duncan was her first pick, Trent is once again jealous of Gwen, who retaliates by picking "the beautiful" Lindsay for his team first. Gwen's comparatively casual choice of Duncan made her realize that Trent was now trying to make her jealous of him, which leaves her shocked. Trent's behavior in this episode continues to surprise Gwen as he outright calls her and Duncan "punk wannabes" when Duncan catches Gwen when she falls from the steep hill, having the other Killer Grips gasp in shock as Gwen and Duncan become gravely annoyed. Gwen tries to keep her cool and focus on defeating the whole opposing team rather than just Trent. Through this, Gwen's team wins the first challenge. Gwen later assures Trent that she has no romantic feelings for Duncan, who she says keeps a secret photo of Courtney under his pillow.

Gwen and Duncan hug in Beach Blanket Bogus.However, in Beach Blanket Bogus, Trent begins to act strangely as he becomes oddly particular about the strangest things, such as how many eggs he has on his plate. Duncan has now resorted to pranking him, but seems to have no real animosity towards him and is just poking fun at him for his obsession over Gwen. When Gwen's team wins their first challenge, she gives a friendly hug to Duncan, convincing Trent, (in his eyes), that Gwen would eventually betray him. When the cast return to Total Drama Island for the remainder of their beach-themed challenge, Trent's obsession for Gwen reaches new levels (now interfering with the challenge and weirding out his teammates) in wanting to name the Killer Grips' sand castle after her, as well as doing absolutely everything nine times. Gwen realizes the significance of the number when Duncan points out that the number of letters in her name combined with the number of letters in Trent make up nine. Harold adds that the obsession with the number started when Trent first took an interest in Gwen. This causes her to freak out when Trent tries to strike up a conversation with her and she discovers him carrying nine branches. Later, Trent throws a dance-off challenge against LeShawna, believing that Gwen would be saddened if her team lost. Gwen feels responsible for causing his mental distress. The two have a private chat in the forest where they iron out their problems. As they are about to kiss, Owen reveals himself in wanting to see them make out. They respond by throwing branches at him.
Trent helps Gwen after her painful landing.Despite Gwen's attempts to keep the relationship together, she officially breaks it off with Trent in 3:10 to Crazytown as he continues to throw challenges for her sake while she simply wants to win the competition fair and square. Seeing that the obsession for her was changing Trent for the worse, Gwen gently ended their relationship. However, Justin overheard this and called Gwen out on cheating to win. He exposed the situation to the entire Killer Grips team, whom initially did not believe that Gwen would resort to such measures, but Gwen shamefully admits to her being in the wrong by not resolving the situation sooner. Justin and the others found it hard to trust Gwen until she told them specifically to vote off Trent in order to prove that she honestly wanted to win the right way. The team did as Gwen instructed, thus eliminating Trent from the competition without even having a chance to say goodbye to Gwen. Gwen, however, is shown a video of Trent being escorted out via Chris McLean, who simply did it just to make Gwen feel even worse about what she had done. It remains to be seen when or if the relationship will be touched upon or resolved in the future. Due to Gwen allowing things to get out of hand this far in the competition, she now apparently "owes" the Killer Grips (at the insistence of Justin) even after following her advice to vote Trent off, as a result, Gwen and Justin become closer enemies.

In The Aftermath: I, there seem to be only a few people who agree with Gwen's decision to break up with Trent and get him voted off the show. At the end of the episode, the only people of the non-participating contestants that seem to still agree with her are Cody and possibly Geoff (who was her most vocal supporter). He may or may not have changed his mind after making up with Bridgette (who was an avid Trent supporter from the beginning, despite Gwen being one of her best friends) and hearing Trent's side of the story. This turn of events indicates that Gwen has become somewhat unpopular amongst the show's contestants, despite proving to be such a competent and honest competitor.
Gwen leaves Total Drama Action with a smile.Gwen and DJ became good friends in Total Drama Action.In The Chefshank Redemption, Gwen starts owing the Killer Grips throughout the prison challenge. Heather was suspicious about her and keeps accusing Gwen of trying to make their team lose. During the escape tunnel challenge, Gwen slows her team down by faking claustrophobia and whacks Harold on the head with a gold shovel. As it was down between Gwen and Heather for the final Gilded Chris Award, Heather gets the trophy and heads up to the podium to tell everyone what a loser Gwen was. In the confessional, Heather, Harold, and LeShawna voted her off. LeShawna and Harold both voted off Gwen for the shovel incident. As she was being handcuffed by Chef in order to head to the Lame-o-Sine, Duncan offered to take Gwen's place, as a way of saying he really wanted to be out of the competition, but was quick to say that he was just kidding when Chef agreed to it. Gwen tells Duncan he won't get out of the competition that easily and wishes him lots of luck. In the confessional, it was revealed that the Grips ordered Gwen to vote herself off the show. Gwen is the first contestant from the Screaming Gaffers to get voted off, and the first person to ever vote their self off in the Total Drama series.

In One Flu Over the Cuckoos, the Screaming Gaffers have learned about Gwen cheating on behalf of the Killer Grips, though they do not yet know that she was blackmailed into doing so by Justin. It has yet to be seen how this affects her relationship with the other Gaffers.
Courtney accuses Gwen of stealing Duncan away from her.In The Aftermath: II many of the other contestants (especially Courtney, Katie, and Sadie) and most of the audience seem to not like Gwen much anymore as she is booed by the whole audience when she comes out on stage, with everyone believing that Gwen had sold out Trent to stay in the competition instead of just taking a break from him. She is criticized by everyone for the way she broke up with Trent. Throughout the show she states that she does still cares deeply about Trent and likes everyone on the show, and truthfully states that she and Duncan are only friends. This however, does not get through to Courtney as Geoff, for his own amusement, manipulatively displays an off-screen scene in which she and Duncan allegedly almost kissed. A jealous Courtney, who refuses to see that Gwen is telling the truth about herself and Duncan, chooses to believe Geoff, and is infuriated, thereby sealing her rivalry with Gwen. When Gwen is about to go into a piranha-infested dunk tank at Geoff's insistence, Trent helps stop it and says he did cheat so he knew he would be kicked off. Trent's intervention allows him and Gwen to make up with each other, as she thanks him and apologizes for what she did to him. Trent returns this, saying they are even. However, their relationship has yet to resume if it does so.

Gwen is mentioned in One Million Bucks, B.C. because of her relationship with Duncan. Throughout the episode Courtney tells off Duncan about his "close friendship" with Gwen, assuming that Duncan purposely tried to hook up with her. Duncan truthfully denied this at all times, along with admitting he is still crazy about Courtney. Gwen appears again in The Aftermath: III, now as a commentator sitting next to Trent. However she has no lines in this episode. In Mutiny on the Soundstage, Gwen is shocked along with the other contestants about the tie between Duncan and Beth.
Gwen does not reveal her vote to the viewers.Like everyone else, Gwen is seen again in The Aftermath: IV. She gets embarrassed when Trent plays the guilt trip while asking his question. Later, she gets her chance, and asks the two finalists "what would they do with the money to help the environment when they're not thinking of themselves." Gwen likes Beth's answer, until Duncan says his answer and she then says she knows who her vote goes to. Gwen is later seen in the voting stall where she says she won't show her vote as she doesn't want to be seen as "predictable." Gwen is seen smiling when Duncan wins, but doesn't really "cheer" along with everyone else (the same is in the alternate ending where Beth wins).
Gwen and her blog show.It's revealed in Celebrity Manhunt's Total Drama Action Reunion Special that after Total Drama Action, Gwen began a web show to talk about her time with the cast and to help the environment. Katie and Sadie joined her as her assistants (though they would speak before they were supposed to). This implies that they are not mad at her anymore. The show soon came under attack by Heather, who mocked the show with her own web video. This caused Gwen to lash out with secretly recorded footage. The two were brought into Celebrity Manhunt's studio for an interview, only to get into a fist fight. The two join everyone at the red carpet show, only to find that Chris is starting a new reality show. Gwen teams up with the rest of the cast to stop Chris and his new team, but their efforts are in vain when Courtney drives the bus off a cliff. Gwen is amongst the people rescued by Chris and proceeds to Total Drama World Tour (thinking this may be her season).

Gwen is motivated to sing to avoid being eliminated instantly.In Walk Like An Egyptian - Part 1, Gwen got off the bus after Heather, and called Heather's hair fake. Duncan makes a joke about Heather's hair as well, and Gwen laughs. This scene shows that Gwen is still friends with Duncan, much to the disgust of Courtney. At first, Gwen refused to sing, along with Duncan, but after Bridgette read the rules of the competition and Cody persuaded her, Gwen changed her mind and sang along with the others. During the challenge, Gwen was climbing the pyramid by herself, until Duncan offered for her to join him and Courtney. Gwen and Courtney started arguing all the way up to the top of the pyramid, which lead to Duncan becoming highly annoyed with the two and causing him to quit. Gwen, along with Courtney, were both sad when Duncan decided to quit. Gwen was placed on Team Amazon, along with Heather, Courtney, Izzy and Cody.
Gwen sings and dances in Walk Like An Egyptian - Part 2's Lovin' Time with her worst enemies.In Walk Like An Egyptian - Part 2, Gwen was still shocked about Duncan quitting, Cody tries to hit on Gwen, since Trent is gone, but Gwen only thanks him about helping her get closer to Trent. During Lovin' Time, Gwen sings as a part of a trio including Courtney and Heather during the song, but has no solos. Gwen laughs at Heather, when she tells the rest of the team that they should listen to her more. Gwen and her team get lost on their camel and causes them to arrive at the Nile last. After Sierra switches onto Team Amazon by giving away Izzy, the team is able to cross the Nile easier, but aren't able to get their camel onto their boat until Alejandro requests Izzy to help them out. During Rowin' Time, Gwen has minimal participation, but has a small solo, pleading the crocodiles to let them reach the shore. Gwen, and the rest of her team, were able to cross the finish line first and escape elimination, since they held on to their camel.
Gwen and the rest of her team win the challenge.In Super Happy Crazy Fun Time Japan, Gwen, Courtney and Heather are still on bad terms with each other. Gwen says to Courtney that they don't need a team leader, because they are already winning. Gwen had two solos in Before We Die. During the first challenge, Heather suggested that Gwen does it, adding Gwen's face needing "remodeling", Gwen reminds Heather that they are on the same team and to flip the "witch switch" off. Gwen, Courtney and Heather fight over what they should make their commercial about, which ends up in the three storming off. When Chris asked for the Amazon's commercial, Gwen stated that this was very humiliating. But suddenly, Cody and Sierra appear saying that they did a commercial. Cody and Sierra win the challenge for Team Amazon, as Chef liked their commercial because it had exploding donuts. In the end, Sierra cheered with a group hug with Cody. Gwen, along with Courtney and Heather, were about to join the hug, but Sierra told them to "back off". Then later team Amozon met thier newest member Dashawn.
